Direct freezing double-system double door refrigerator with freezing chamber at upper part

Abstract

The invention discloses a direct cooling double-system double-door refrigerator with a freezing chamber at the upper part. The refrigerator comprises a freezing chamber at the upper part and a refrigerating chamber at the lower part which is seperated by a central beam, and a freezing evaporator and a freezing evaporator board therein used in the freezing chamber, a refrigerating evaporator and a refrigerating evaporator board used in the refrigerating chamber, a refrigerating capillary, a freezing capillary and a three-way piece communicating with the freezing evaporator. The refrigerator is characterized in that: the refrigerating evaporator has a combined pipeline distributed structure for preventing frosting at the back of the refrigerating chamber. The combined pipeline distributed structure is provided with a refrigerating inlet section, a middle refrigerating coil pipe and a refrigerating straight pipe, and further provided with a rear refrigerating section for compensating the balance bending, and a refrigerating outlet section with a solution storage cushioning structure. The direct cooling double-system double-door refrigerator with the freezing chamber at the upper part of the structure has an obvious function of stopping the frosting at the back of the refrigerating chamber caused by liquid returning when direct cooling is adopted after the refrigerating chamber stop working.

Description

technical field [0001] The invention relates to a double-door refrigerator, in particular to a direct-cooling double-system double-door refrigerator frozen on top. Background technique [0002] Typically, a double-door refrigerator includes a freezer and a refrigerator. The structure of the refrigerating device of a traditional double-door refrigerator includes a compressor, a condenser, a capillary tube, a freezing evaporator and a refrigerating evaporator, which are connected in sequence according to the refrigerant running direction, forming a refrigeration cycle. The refrigerating evaporator and the refrigerating evaporator of this refrigerating device are connected in series to run synchronously, and the temperature of the freezing chamber and the refrigerating chamber cannot be adjusted separately. For this reason, after gradual improvement, there are dual-system direct cooling refrigerators with the bottom of the freezer, air-cooled dual-control refrigerators with th...

AI Technical Summary

Problems solved by technology

Since the implementation of the direct-cooling dual-system double-door refrigerator on the refrigerator has many technical difficulties that cannot be overcome, it has always been a blank in the refrigerator industry.

The main technical difficulty or main disadvantage of implementing the direct cooling dual-system double-door refrigerator with the freezer on top is that users who are accustomed to using the freezer on the top cannot enjoy direct cooling refrigerators with independent control of refrigeration and freezing

There is no way to precisely control the temperature individually, and you can't turn off the refrigerator when you don't want to use it

[0013] Because the direct-cooling dual-system double-door refrigerator is frozen on the top, when the temperature is controlled separately, the refrigeration is turned off separately, and the freezer is used alone, when the refrigeration is stopped and the direct cooling is frozen, the liquid backflow will cause frost or ice on the back of the refrigerator

In order to eliminate the problem of frosting or freezing on the back of the refrigerator, it can be solved by moving the position of the capillary injection, or setting the heating wire on the refrigerator evaporator, and reheating the pipeline and defrosting pipe, etc., but it will cause a lot of energy consumption
